First, you should know that the majority of wearers of soft contact lenses choose these daily disposables. They are easy to adapt to and being soft they are very comfortable. Of course, daily disposables are very easily torn, because they are for one-time use only. The other advantage to daily disposable contact lenses is that disinfecting or soaking is not necessary since they are sterile when they are delivered straight from the package and will not be re-used. On the other hand, for those who want to wear contact lenses overnight, extended wear lenses are the best choice as they are designed with that in mind. They require little or no cleaning and are available in tints and bifocals. If instructions are followed, there is very little likelihood of infection. But they also have fatal flaws. It will be infected easily. So they can damage your eyes if you ignore this kind of problem. In short, no matter which type of contacts you will choose, you'd better consult an eye doctor.
